4 Claims. (c1. 4-241 This invention relates to a toilet seat lifter and more particularly to such a device which acts to automatically lift the seat of the toilet whenever the seat is not in use and the cover .is in raised position or no cover is provided.

Many cities and other governing bodies have enacted legislation requiring that the toilet seats of public restrooms be kept in a raised position whenever the toilet is not in use. Such laws and regulations are oftennot enforced because there has been no inexpensive automatically operating toilet construction of such kind avail-. able.

It is an object of my invention to provide, a device which is adapted to. accomplish exactly what such laws and regulations require for the health and sanitation of the public. With my device, the toilet seat is automaticallyraised whenever it is not in use if either the cover is in raised position or no cover is provided.

- It is a further object of my invention to provide such a. device which is soeconomical that it can be purchased by the owner of every public place and which is so simple to-install that virtually anyone can easily place it in use.

Another object of my invention is to provide such adevice whichis universal in', two senses. First, it will fit any size or style of toilet seat construction now in use,

regardless of the height of the toilet seat hinge pin from the top or the toilet bowl. to provide different degrees of spring tension to lift a toilet seat of any weight-now in use. This universality is achieved without any change in the construction of the device, only one model of which is made and sold to the public.

My invention also comprises such other objects, advantages and capabilities as will later more fully appear and.

which are inherently possessed by my invention.

While I have shown in the accompanying drawings av preferredv embodiment of my invention, it should be'understood that the same is susceptibleof modification and change without departing from the spiritof my invention.

of the component parts of my toilet seat lifter in the positions which they occupy in use;

' Fig. 2 is' a front elevational view of my toilet seat lifter in use, with the conventional toilet seat construction shown in dotted lines;

' Fig. 3 is a sectional view taken on line 3--3 of Fig. 1, showing my toilet seat lifter in use, with part of the conventional toilet seat structure shown in dotted lines.

A preferred embodiment which has been selected to illustrate my invention comprises a pair of identical coil springs .10, which are preferably formed of 12 gauge spring steel. The coils of springs are closely wound-to form a tube having an inside diameter slightly larger than the outside diameter of a conventional'toil'et seat hinge pin, so that the coil springs 10 can be slidably mounted thereon. A

Each of coil springs 10 comprises approximately eight turns of wire. One end 'of each of coil springs10comprises a straight end 11, while the other end comprises a right angle end; "The right angle end is formed by a straight portion'lz' which leaves coil spring 10 at an angle perpendicular to straight end '11" and which bends at a Second, it can be adjusted Referring to .the drawings, Fig. l is a top plan View parallel to straight end 11, but in the opposite direction.

Coil spring 10 is thus provided with ends which extend in opposite directions from each other. Straight end 11 extends in a line with one circumferential edge of coil spring 10, while hook portion 13 is positioned somewhat beyond the opposite circumferential edge of coil spring 10.

A tension plate 14, which is preferably formed of steel or other suitable material, comprises a flat base 15 and an upright portion 16 which is integral therewith and which extends upwardly along the front edge of tension plate 14. Upright portion 16 is bent to form an angle with base 15 which is somewhat less than a right angle. Upright portion'16 thus extends upwardly and slightly rearwardly along the front of tension plate 14. Base 15 is provided adjacent its opposite ends with a pair of U- shaped slots 17, which extend from the rear of base 15 almost to upright portion 16.

My device may be installed by first loosening the nuts on the ends of the bolts which hold the toilet seat hinge to the toilet. hingle bolt flanges so that the U-shaped slots 17 fit around the hinge bolts.

The screws. holding one of the hinges to the bottom of the toilet seat are then removed, permitting the hinge pin to be partially removed. The coil springs 10 are placed on the hinge pin in such a manner that their straight ends 11 extend downwardly, while their hook portions 13 extend upwardly- The straight ends 11 are positionedin front of upright portion 16. Coil springs 10 are positioned adjacent the opposite ends of the hinge pin.

Straight ends 11 and upright portion 16 will engage over a considerable range of variations .in the distance.

These ends of coil springs 10 thus form a right angled hook which engages the bottom corner of the toilet seat.

The amount of tension in coil springs 10 can be con-' trolled by the positioning of tension plate'14. If tension plate 14 is moved forwardly, upright portion 16 will tend to act against the coil springs. If tension plate is moved rearwar-dly, there will be less tension in coil springs 10.

lt isjthus possible to adjust the amount of tension so that my device will operate properly with any weight of toilet seat.

. The hinge bolts may be temporarily tightened until the tension is properly adjusted. After this has been done, the hinge bolts are completely tightened and the screws replaced to fasten the hinge to the bottom of the toilet.

seat.

After installation, my device through coil springs 10 provides a tension which normally tends to move thev The seat toilet seat upwardly from the top of the toilet. may be held down only by use or by the weight of the toilet seat cover, which counteracts the force of coil springs10.

In use, my device converts a conventional covered or coverless toilet seat into one which is automatically raised when not used or covered.
